A herpes-like virus infects a non-ostreid bivalve species: virus replication in Ruditapes philippinarum larvae ArchiMer
Renault, Tristan; Lipart, Cecile; Arzul, Isabelle.
Sporadic high mortalities were reported in June 1997 among hatchery-reared larval Manila clam Ruditapes philippinarum in a French commercial hatchery. Cellular abnormalities were observed in semi-thin sections in affected animals. Transmission electron microscopy revealed the presence of herpes-like virus particles in larvae. This is the first description of a herpes-like virus infection in larval R. philippinarum, a non-ostreid bivalve species. Virus particles were similar to other herpes-like viruses described from different oyster species with respect to ultrastructure and morphogenesis. Electron microscopic examination also demonstrated cells with condensed chromatin and extensive perinuclear fragmentation of chromatin. Like viruses infecting oysters,...

Analysis of shell colour determinism in the Manila clam Ruditapes philippinarum ArchiMer
Peignon, Jean-marie; Gerard, Andre; Naciri, Yamama; Ledu, Christophe; Phelipot, Pascal.
The Manila clam presents a large polymorphism for shell colours and patterns. No experiment has been conducted to study the determinism of such a polymorphism which has been well known for a long time. The aim of this study was firstly to determine the genetic variation for shell colour and secondly to produce some homozygous lines for the shell colouring. These lines could then be used as controls for laboratory experiments. The colouring is defined by three characters: asymmetry, ornamentation and hue. Clams with asymmetrical colouring are not fully pigmented, except for a posterior band on the left valve. Clams with symmetrical colouring are fully pigmented on the two valves. Four cross series were conducted between the different characters: Asymmetry...

Campagne d’évaluation du stock de palourdes du bassin d’Arcachon. Année 2018 ArchiMer
Sanchez, Florence; Caill-milly, Nathalie; Lissardy, Muriel.
This report details the results of clam stock assessment survey, which took place between 14 May and 17 June 2018 in Arcachon Bay. Co-organized with CDPMEM33, with financial support from DLAL FEAMP Arcachon Basin Val de l'Eyre, Nouvelle-Aquitaine region, the CDPMEM33 and Ifremer, the clam stock assessment and its characteristics were provided. The samples were collected from 533 sampling stations distributed over an area of 52 km², with an Hamon grab, using a generalized random tessellation stratified spatially balanced design (GRTS). Venerupis philippinarum remains the dominant species with 99 % of the population. The size distribution of Manila clam is in the range 5 – 41 mm with a main mode around 24-28 mm. In 2018, the mean densities are 39 individuals...

Development of culture techniques for new bivalve species ArchiMer
Bodoy, Alain; Mercer, J. P..
Were are two main reasons for the development of cultivation techniques of new bivalve species. First, the risk exists that traditionally reared species may be ereadicated or severely depleted by pathogenic agents. For example the Portuguese 0yster Crassostrea angulata. disapeared from the French coasts in the early 1970's and worldwide production of the flat oyster, Oslrea edulis has been dramatically reduced by the effects of Bonamia. Secondly, in some countries production may he self-Iimiting by the size and availabilily of national and international markets and a wider species range could offer some promising new economic opportunities for aquaculturists. In particular this applies to species where there are identifiable market shortfalls.

Essai de traitement du sédiment contre le vibrio P1, lors d'un demi-élevage de palourdes dans la zone des Abers. ArchiMer
Barret, Jean.
Different treatments aiming to cure the grounds, which bad been contaminated by the vibrio P1 "brown-ring", have been carried out on some sites of on-growing, taking place in the Aber Benoit, in Brittany. The tested products were Lime, and an antiseptic "Agroseptil" which positive effects are admitted in pisciculture. The results (growth, survival and the presence of brown-ring), do not point out any difference between the various treatments. However, it looks as if the brownring has appeared latter than on other clam-fields located in the same area.This effect does not seem to be due to the various treatments of the soils, but to the antibiotic  bath of the clams bef ore seeding.

Etude expérimentale de la prédation de la palourde japonaise, Ruditapes philippinarum, par la dorade royale, Sparus aurata, et le baliste, Balistes capriscus ArchiMer
Robert, René; Parra, René.
Depuis 1988, d'importantes mortalités de palourdes japonaises Ruditapes philippinarum ont été enregistrées, sur de nombreux élevages, dans le bassin d'Arcachon. Pour expliquer celles-ci, l'hypothèse d'une prédation par la dorade royale Sparus aurata et par le baliste Balistes capriscus était avancée. Afin de la vérifier, une étude expérimentale de la prédation de la palourde par ces deux poissons a été réalisée en laboratoire. Si les relations taille prédateurs-taille proies sont plus marquées chez le baliste, les deux espèces sont particulièrement voraces, puisqu'elles s'avéraient capables de consommer, en 24 h, 500 petits naissains et 350 jeunes palourdes de 25 mm de longueur, 50 % à 70 % des proies étant consommés au cours des 6 premières heures....

Etude technique et économique de la filière de production intensive de la palourde japonaise Ruditapes philippinarum en marais ArchiMer
Baud, Jean-pierre; Paquotte, Philippe; Ayel, Jean-philippe; Lepage, Claude.
A 20 g clam total weight was reached in 19 months at a 300.m-2 density using a mixture of sea water and Skeletonema costatum algae. Currently, initiating an intensive ongrowing clam business is not economically viable since the marketable value is at a record low of 30FF.kg-l . Phytoplankton production and sea water pumping cost effectiveness should be improved. However, a company's activities may be diversified using intensive clam rearing techniques but without labor staff increase.

Relations entre l’état d’une ressource et son exploitation via la compréhension et la formalisation des interactions de socio-écosystèmes. Application à la palourde japonaise (Venerupis philippinarum) du bassin d’Arcachon. ArchiMer
Caill-milly, Nathalie.
Significant component of the marine benthic ecosystem, exploited bivalves are mainly located inside the coastal area, which temporal and spatial features generate natural population fluctuations and contribute to considerable biomass and demographic structure changes added to anthropogenic activities’ effects (fishing, pollution,…). Understanding of the relationships between the species, its environment and its exploitation is crucial and their formalization, including for management purposes, requires development of mathematical models that aim at describing the functioning of the system, to explain the observed phenomenon in terms of cause and effect or predict effects of new causes. Originating from venerid culture trials carried out in France in the...

REPAMEP - Réponse des palourdes aux stress environnementaux combinant métaux, efflorescences toxiques et pathogènes - Programme LITEAU. ArchiMer
Baudrimont, M.; Gonzalez, P.; Hegaret, H.; Khayati, Alice; Lassus, Patrick; Legeay, A.; De Montaudouin, Xavier; Raymond, N.; Soudant, P.; Tran, D..
The originality of this project consists in the interdisciplinary approach gathering the impact of toxic phytoplankton blooms and metallic pollution on health (behaviour, stress, immunity, genetic) and disease development of the Manila clam, an economieally important species. The Manila clam Ruditapes philippinarum is the second exploited bivalve in the world. It was introduced in Arcachon bay during the 80's and is today exploited by professional fishermen (57 licences). A 50% decrease of the stock was observed during the last five years. Beyond fishing pressure, a PhD thesis identified several diseases as potential threats, like perkinsosis (=Dermo) and brown muscle disease (BMD). The project confirms the settlement of these pathologies with high...
